- Consider a market in which supply depends on current price qt = b0 + b1pt + ut b1 > 0 while demand depends not only ont he current price, but also on the price rationally expected to prevail in the near future: qt = a0 + a1pt + a2Etpt+1 + vt Here a1 < 0 and a2 > 0 while ut and vt are white-noise disturbances. Find solution for pt.A printer manufacturer estimates that the average purchaser of a printer will also purchase six ink refills over the lifetime of the printer. The relevant data are: Printer: price: $400, margin: $100 Refills: price: $40, margin: $30 The manufacturer is considering increasing the price of printers by 10% to $440. What volume decrease in the sales of printers is the stay-even sales change for the firm? (Ignore the issue of discounting the value of future ink refill sales. Imagine, for example, that all six are purchased upfront with the printer). A. 11.5% B. 12.5% C. 13.5% D. 14.5% Use = % Q = (Pold - Cold)/(Pnew - Cold) - 1How can we be sure that the price P is the same for all vehicles?

- Suppose market demand and supply are given by Qd = 100 − 2P and Qs = 5 + 3P. The equilibrium quantity is:A small countertop installing company hires you to estimate their customers weekly demand function for marble (per sq ft). The demand function is as follows: Qm=5000-30Pm +20Pg + 0.05Inc m=marble, g= granite, inc = avg disposable income for home improvements in the surrounding area. Current prices: marble = 40, granite = 25 and disposible income = 5000 Suppose during the supply change shortage the price of marble triples to $120 Determine the elasticity of demand at the new market price for marbleThe rebound effect refers to the tendency of motorists:a) to purchase fuel efficient cars when the price of gas increasesb) to neglect efficiency considerations in purchasing a car when the price of gas is lowc) to drive more when increased fuel efficiency decreases the per kilometer costs of drivingd) to switch to lost cost fuels when gas prices increasese) none of the above
- A manufacturer of computer workstations gathered average monthly sales figures from its 56 branch offices and dealerships across the country and estimated the following demand for its product: Q = +15,000 - 2.80P + 150A + 0.3Ppc + 0.35Pm + 0.2Pc The variables and their assumed values are Q = Quantity P = Price of basic model = 7,000 A = Advertising expenditures (in thousands) = 52 Ppc = Average price of a personal computer = 4,000 Pm = Average price of a minicomputer = 15,000 Pc = Average price of a leading competitor’s workstation = 8,000 Compute the elasticities for each variable. On this basis, discuss the relative impact that each variable has on the demand. What implications do these results have for the firm’s marketing and pricing policies?Bread demand function: Q = 100 + 0,5 1 - 30P1+ 20P2, where Q is the annual value of demand; I is income; P1 is the price of bread; P2 is the price of pasta.
